Title: Improvements in electromagnetic brakes
IPC: F16D55/36
Filed: 1953-09-30
Abstract: 779,349. Electromagnetic brakes. LETOURNEAU, R. G. Sept. 30, 1953 [Oct. 17, 1952], No. 26863/53. Class 103 (1). In a spring applied, electromagneticallyreleased brake, drag between the rotor and stator friction members is prevented, when the brake is energized, by the provision of non- magnetic studs 14 threaded into end bell structure 3 of motor 1 to support axially movable magnetic pressure plate 16 and support means 18 for the stationary brake friction elements 23, so that the flux density in the friction members is reduced and the lines of force seek the shortest possible path back to the pressure plate 16 and support means 18, thus moving the friction members towards the right out of frictional engagement with the rotatable friction members 24 splined to rotatable hub 11 and motor shaft 7. The brake is applied by springs 15 and released by the energization of coil 28 placed in the end portion 6 of the end bell structure 3 bolted to casing 2 of the motor. The end bell structure serves to house the coil 28 substantially in the same plane of the bearing 8 such as to reduce the overall length of the brake. Specification 741,921 is referred to.

Title: Methods and apparatus for the manufacture of cellular cushioning materials
IPC: B29C49/00
Filed: 1974-06-18
Abstract: 1478535 Inflated cellular laminate; seaming non-metallic sheet material C T TROY 18 June 1974 [18 July 1973] 27012/74 Headings B5N and B5K Closed-cell cushioning material is formed from a "prefab", comprising superposed thermoplastic sheets which are sealed or are integral along two opposed margins 44 and which have spaced cross-seals 46 extending between the marginal seals but spaced from them, by inflating the unsealed spaces, limiting the degree of inflation along lines extending across the cross-seals, and heat-sealing along said spaced lines 88. The sheets may be clear polyethylene films and may be coated with polyvinylidene chloride. As shown in Figs. 3 and 4, a prefab is subjected to widthwise distortion by intermeshing curved pins 55, 57 to introduce slackness and an inflating gas, e.g. air, is introduced via slotted guide tubes 73. Inflation is limited by forming bars 61, 62 and longitudinal sealing is carried out by sealing bars 67 and reciprocating pressure bars 68, using impulse sealing or continuously-heated sealing bars. The sheets are intermittently advanced and sealed whilst stationary, and are maintained under tension by rollers 78, 82 and braked rollers 49, 50. The guide tubes 73 are provided with knives 75 for slitting the marginal seals 44 after sealing. In an alternative embodiment (Figs. 7 and 9) the sealing and pressure bars are replaced by a series of lands 106, 138 on fluid-containing tanks 100, 128 (the latter being reciprocable). The lands 106 have a rubber strip 108, a tensioned heating ribbon 110 and a continuous glass cloth strip 124 for impulse-sealing. The lands 138 have a rubber strip with a groove 136, which prevents dissipation of heat and thus provides a strong seal in the centre of the sealing line 88. cooling is by an air-blast and/or by fluid circulating in the tanks. In Fig. 12, the groove is replaced by a space between strips 158, 160 and communicating with a series of outlets 162 for directing cooling air from tank 128. In a further embodiment (Figs. 13-16, not shown) the seals 88 are formed continuously between circulating sealing and pressing bands. The sealing bands are successively disposed against corresponding ridges of (i) an oil-filled heated tank and (ii) a tank in which cooling fluid circulates. The pressing bands become operative by bringing a series of bars into contact therewith, a control circuit being shown for doing this. The prefab may be made (Fig. 1, not shown) by passing two sheets around a roll on which the marginal seals 44 are formed by suitably-disposed radiant or flame heaters and, whilst being gripped between tensioned, optionally heated endless belts, around a roll provided with continuously-heated sealing bars for forming the cross-seals 46 and around a cooling roll.

Title: Improvements in production of hydrogen peroxide and catalyst therefor
IPC: C01B15/023
Filed: 1950-11-06
Abstract: Palladium supported on activated alumina is employed as a catalyst in the hydrogenation stage of a cyclic process for the production of hydrogen peroxide by reduction and oxidation of alkylated anthraquinones, particularly 2 tertiary butyl anthraquinone, preferably employing as a solvent a mixture of a prmary or secondary nonyl alcohol such as di-isobutyl carbinal or 3.5.5 trimethylhexanol-1, and a substituted naphthalene such as alpha methyl naphthalene.  Other suitable intermediates referred to are 2 ethyl, 2 isopropyl, 2 sec. butyl, 2 sec. amyl and 1.3, 2.3, 1.4, or 2.7 dimethyl anthraquinones together with the corresponding tetrahydro-anthraquinones.  The catalyst may be employed as a fixed bed which is regenerated in situ, or held in suspension in the working solution by mechanical agitation or by upflowing hydrogen, a mild agitation being preferable Spent catalyst is withdrawn and regenerated by treatment with an aqueous alkaline solution of an oxidizing agent, which may contain up to 50 per cent of a water miscible solvent to assist the solution of the oxidizing agent which may be alkali or alkaline earth metal chlorites or hypochlorites, organic hypochlorites, per compounds of general formula ROOH where R is hydrogen or a hydrogen radical.  Alkali metal peroxides, perborates, carbonate or phosphate perhydrates, urea peroxide or organic peracids may also be used, the preferred oxidizing agents being sodium chlorite or hypochlorite, peracetic acid and tertiary butyl hydroperoxide.  When hypochlorites are employed it is preferred to follow the reactivation with a hydrogen peroxide wash and a treatment with formaldehyde to ensure complete resolution of palladium oxide to the metal.  The catalysts may be prepared by suspending the alumina in an aqueous acid solution of palladous chloride and adding formaldehyde and sodium bicarbonate successively, or by reducing chloropalladous acid with hydrogen, to give a palladium content of 0.1 to 2 per cent by weight.  The efficiency of the catalyst in the process is compared with that of palladium supported on silica-alumina, activated coconut charcoal, active carbon prepared from coal or liquin, deodorizing carbon, corandum and silica gel.  Specifications 465,070, 686,567 and 686,572 are referred to.

Multiple machines; sound-boxes, arrangement of; tone-arm joints; disc records. - Music produced by a number of performers, such as instrumental and/or vocal music, is recorded by making separate records of the parts, e.g. a song and its accompaniment may be recorded, simultaneously or otherwise, on opposite faces of a disc, or parts rendered by various instruments &c. may be recorded in groups on two or more record-surfaces, which may be on separate synchronously-driven - discs. The individual or group records thus obtained are reproduced simultaneously. The Figure shows a reproducing machine for a record made as described above, in which sound-boxes 1 work simultaneously on opposite sides of a record 15. The sound-boxes are mounted on connected tone-arms, 2, 3 which are doubly jointed at 6, 7 for vertical and horizontal movement. Passages 5 lead from the tone-arms to a common horn 12, at the inner end of which is a movable obturator 14. When the part records are made on separate discs, these may be rotated on one and the same axis, or on separate axes. Separate horns may be used in the reproducing-machines, and by providing a sound-controlling device in each, the volume of sound from the part records may be controlled individually. Instead of ordinary sound-boxes, other sound-reproducing or transmitting devices such as microphones may be used.

Abstract: 1,173,564. Gyroscopic systems. ELLIOTT BROS. (LONDON) Ltd. June 13, 1967 [June 17, 1966], No. 27234/66. Heading G1C. A gyroscopic system for use in aircraft comprises at least two gyro rotor 3, each mounted for spinning in its own individual inner gimbal ring 4 and a common outer gimbal ring 8 itself pivotally mounted, each gyro rotor being arranged so that it can give an individual signal from synchros 9, 10 on the occurence of an angular movement about the pivotal axis of its own inner gimbal ring whereas an angular movement of one inner gimbal ring about the pivotal axis of the common gimbal ring 8 will communicate an equal angular movement about that axis to the or each other inner gimbal rings. The signal from synchrose 9, 10 if fed into a comparator 11 and should the two synchos differ by more than a predetermined amount the comparator initiates an alarm signal by way of line 13. The outer gimbal ring 8 is pivoted on a shaft 14 carrying further synchos 15, 16, the signals from which are fed to comparator 17. The two gyros 1, 2 have different characteristics. When all parts of the system are functioning correctly, the main gyro 1 will operate in the conventional manner. However if there is excessive friction in the roll pivot 14, the gimbal ring 8 rotates which will cause by gyro rotors to precers about their pivots 6, 7 at different rates. If the difference is sufficiently great an alarm signal will be given. If there is excessive friction in one of the pivots 6, 7, the gimbal ring 4 of the affected gyroscope will rotate causing precession about the pivot 14 resulting in movement of the other gimbal ring and again causing an alarm signal to be given. In a second embodiment there are provided two further gimbal rings mounted between the inner gimble ring and the common ring to reduce friction in the system, the inner gimbal ring being connected by a servo-system to its next but one ring and the common ring being connected to the second ring from the rotor i.e.the rings with common axes are connected to each other.
